2 Claims.

This invention relates to a window fixture, applicable to the sides or lambs of a conventional window frame, adjacent the outer side of the sash, primarily serving as a combined grille, insect screen and air filter as a protective means for the window opening, and readily convertible into an outwardly projected platform or ledge for supporting an individual either seated or in erect position for convenience and safety in cleaning 1e outer side of the panes of the window sash or other service or to extend the platform section into the room for service as a table leaf.

An object of the invention is to provide a grille for window or like opening of simple and durable structure, readily applicable to the conventional window framing at the exterior side of the sash, and primarily as a protective guard and screen particularly for the lower sash area and readily convertible into a platform or ledgeto extend either outwardly, orinwardly of the window frame. I

The unit as a foldable fixture constitutes a stay section pivotally connected to the window frame, and a grating or guard section pivotally connected to the stay section to swing or fold within the stay section conjointiy extending vertically within the window frame for a window guard and screen, and adapting the sections to be moved to a relatively angular position to provide a horizontaiiy extended platform having a bearing upon the window sill.

Various other features and advantages of the invention will be more fully set forth in a description of the accompanying drawings, ing a part thereof, in which:

Figure 3. is an elevation of the window frame as viewed from the exterior side, fitted with the improved fixture and having the grille section equipped with a wire or woven cloth material serving as an insect screen and air filter.

Figure 2 is an enlarged sectional view taken on line 2--E, Figure 1.

Figure 3 is an enlarged detail plan View of the upper pivoted end of one of the side rails.

Figure 4 is a section taken on line %-(i, Figure 2.

Figure 5 is enlarged section taken on line 5-4, Figure 2.

Figure 6 is a section similar to Figure 2, with the fixture or unit converted into a window platform or ledge.

Figure 7 is a sectional view similar to Figure 6 with the fixture adjusted to bring the grille section inward of the window, to serve as a table.

Figure 8 is an end elevation of the lower porformtion of the fixture viewed from the interior of theroom.

Referring to the drawings, the fixture is exemplified as applicable to the framing of a window opening embodying a conventional window frame, I, employing a pair of sliding sash, as an upper sash, 2, and a lower sash, 3. The fixture has a guard section or grille, 4, for the protection of the lower half of the window opening, or area occupied by the lower sash, and with a similar grille section for the upper half to protect the full window area. The'fixture is located adjacent the outer side of the sash, and in addition to the guard section or grille, i, includes a pair of corresponding side rails ti, 5, each respectively of a length approximate to the full height of the window opening of the frame into which the grille is fitted, except for a slight tolerance to allow vertical movement of the unit to unlatcn the same from a locking connection with the sill, 6, of the. window frame.

The side rails 5, ii, preferably are of angle form in cross section and each is arranged to overlie a relative outer edge andface side of a blind stop, "i, of the window frame, to which the upper end of the rails are pivotally connected. Each rail at its upper end has an elongated slot, 8, through the flange thereof overlying the face side of a blind stop, '6, for the reception of a bolt or pin, 9, extending from a plate, if], fixed to the blindstop. The slot permits the rail to be shifted or moved vertically for uniatching the unit from a pair of lock plates ii, i, fixed to the window sill. In a locked or normal position of the unit, the lock plates prevent outward swing of the grille.

The pivot plate, is, for the side rails is provided with a stop lug, i2, integral therewith and bent at an angle therefrom to limit the outward swing of the rails.

The guard section or grille, comprises a pair of end rails i i, i=3, preferably of channel form in cross section, and positioned with the channel of each inward. The raiis are connected by a plurality of bars 15, extended horizontally, intermediate of and within'the channel of theend rails. The opposite ends of the cross bars; 45, are preferably welded to the end rails for a permanent union therewith. The guard section, at its lower end, pivotally connects with the lower end of the said rails 5, 5, and normally is disposed between and in alignment therewith, and blocked against outward swing of lugs 16, I6, respectively relatively extending inward from the side rails as abutments, against which the upper end of the grille bears. The guard section is locked in its upright position between the side rails by a catch, II, of a conventional bullet type disposed in the channel of an end rail, I4, for engagement into an aperture, I8, in the side rail, 5.

The type of latch or catch is optional and any means may be employed to prevent the grille from being accidentally shifted from its position between the side rails 5, 5.

The lower end of the unit is engaged by a pair of clips, I I, fixed to the sill of the window frame, locking the unit against lateral displacement, unless elevated therefrom. To release the unit it is elevated, permitted by the elongated slots in the side rails, to bring the lower end above the upstanding lugs of the clip, whereupon the unit may be swung outwardly.

The horizontal rods or bars, I5, of the guard section are preferably located at uniform spacing apart, although the number employed and relative spacing is optional. The lowermost bar of the series is free from direct contact with the window sill, to allow the lower margin of the screen fabric to be looped thereabout in its application to the guard section. The screen fabric may be metal, fiber or other material as conventionally employed as an insect guard and a cloth fabric serves admirably as an air filter in addition to an insect screen and may be periodically removed for washing.

The screen fabric when of a fabric material at its opposite longitudinal ends is provided with a hem each for the reception of a binding strip, 20, or otherwise removably secured to the binding strip which for the upper end is removably secured to the end rails, while for the lower end the fabric is looped about the lowermost cross bar of the guardsection bringing the binding strip upon an opposite or inner side, whence it is secured by a draw cord to one of the cross bars, I5. 7

The screen fabric as shown is disposed at the outer side of the guard section, while in the use of a fiber or netting fabric, which is rather limp, it is preferable to interlace the fabrics in a zigzag form about the cross .bars alternately to secure the same against heavy wind pressure, and the side margins of the fabric are tucked in the channels of the end rails.

To convert the unit into a platform or ledge, it is unlatched by elevating the same to raise it above and free it from the lugs I I, I I, fixed to and extending upwardly from the sill and swung outwardly, while at the same time releasing the upper end of the grille from the side rails and swinging it inward and downward to bring it from its vertical position between the said rails, to an approximately horizontal position at an angle to the side rails and resting the free end of the grille upon the stool of the window frame, to which it is locked. Various modes may be employed for locking the grille to the stool, a simple method as illustrated consisting of a pair of slide bolts 2 I, 2 I, fixed upon the stool at the outer side of the end rails of the grille, withthe bolts thereof each adapted to engage through an aperture, 22, in the relative end rail, I4, of the grille. 'In

providing the end rail, I 4 with a plurality of spaced apertures longitudinally thereof, the grille may be set to various adjusted positions, to extend either fully outward or inward or partially so, selective as may meet the needs'of the user. The grille in its use as a platform or ledge may be supplied with a base board, 23, removably sustained thereon and the sash can be lowered to bear thereon.

In the use of the fixture as a platform extending outwardly from the window, various auxiliary features may be added, as an example, a plural section foldable guard rail, 24, as shown in dotted lines Figure 6, may be removably applied to extend upwardly from the platform, as an additional safety measure or to confine the articles placed upon the platform.

The fixture in its normal position is locked to the upper sash when in a fully closed position, by a screw bolt 28, mounted within and extending through a side rail of the upper sash. The screw bolt is adapted to be advanced into a threaded aperture in a lug 29, as a permanent part of a relative side rail, thereby locking both the fixture and upper sash against any sliding action. The lock bolt is preferably located at a point inaccessible from the outside, so that it cannot be maliciously unlocked from the outside, although conveniently accessible from the inside when the lower sash is closed.

In a fixture having an upper grille section, 4a, the screw bolt may be engaged in the threaded aperture in the flange of the channel end rail.

Having described my invention, I claim:

1. A window fixture of the nature disclosed, comprising: a pair of side rails for approximately the heighth of the opening of a window frame, each at its upper end pivotally connected to the window frame, a grille disposed between and at its lower end pivotally connected to the corresponding ends of the side rails, the grille adapted to be disposed in longitudinal alignment with and locked to the rails and therewith, as an unit, providing a guard for the window opening, the grille when unlocked from the rails movable therewith to a relatively angular position to extend the grille transversely to the window frame and have a bearing upon the sill of the window frame to provide a platform, with the rails providing stay supports for the grille.

2. A window fixture of the nature disclosed, comprising: a pair of side rails, each at its upper end pivotally connected to a respective jamb of a window frame, a grille disposed between and at its lower end pivotally connected to the corresponding ends of the side rails, the grille adapted to be disposed in longitudinal alignment with and locked to the rails and therewith, as an unit, providing a guard for the window opening, means for locking the lower end of the unit to the window frame against lateral displacement, the grille when unlocked from the rails movable therewith to a relatively angular position to extend the grille transversely to the window frame and have a bearing upon the sill of the window frame to provide a platform, with the rails providing stay supports for the grille.
